Eve meets her new team and deduces that the murderer is not Villanelle, but a new assassin for the Twelve whom she nicknames “the Ghost”.

While founding wounded Villanelle, Eve is called back to London to investigate a murder case believed to have been ordered by the Twelve. Villanelle has a rough time as she makes her way from a Paris hospital to London.

Villanelle calls Eve to come to the cafe and bring her passport and Konstantin. Eve and Konstantin have a confrontation with Villanelle in a cafe;

Eve investigates Anna, Villanelle’s former teacher, with whom she had a deep relationship before Villanelle killed her husband.

Eve and Carolyn track down Nadia to a Moscow prison, and are allowed to speak to her due to Carolyn’s camaraderie with two Russian Intelligence officers, one of whom is Konstantin.

There are hints that Elena and Kenny may have a romantic relationship. Villanelle breaks into Eve’s home to talk to her, and takes her phone, which Villanelle uses to track down Frank at the safe house and kill him.

Konstantin punishes Villanelle for her recent unpredictable behaviour by making her work with two other operatives: Nadia and Diego. The three are to assassinate Frank Haleton, Eve’s former MI5 boss, who Eve has discovered is a mole.
